What can I do to stop numbness & tingling in hands due to compression of cervical nerve?

You need to have a good workup by a Dr to see exactly what is going on first. If it is indeed a compressed cervical nerve there are a few options you have. Sometimes chiropractic Dr can manipulate the spine and give you relief. If that doesnt work, you might try some injections to the area. The Dr may want to put you on an anitinflammatory drug. They may possible give you a muscle relaxant drug too. Some folks find relief from drugs for pain in the nerve like Lyrica or gabapentin. Opioid drugs usually do not have much effect on nerve pain and really shouldnt be used unless pain is severe and unbearable. As we age, the discs between our vertebrae begin to break down and flatten out, kind of like a jelly donut losing it's jelly and sometimes this can compress nerves. I would try a chiropractor or a DO Dr that does spinal manipulations first. They might be able to decompress the spine enough to stop that sensation from happening.
